Error 522 HTTPS - SSL

all
#1

Currently my website is running on cloudfare with https or ssl will be inaccessible and error 522

#2

My first suggestion is to try setting SSL to Flexible, if it’s “Full” then it contacts the origin over port 443 which it may not support.

#3

Thanks to Jud, I tried turning it flexibly, and testing port 443 is still working normally but the result is a 522 error.

Die you check all the other things mentioned in the KB article? Since flexible didn’t change anything wenn can exclude SSL at this point.
